Hoy was set to compete at the 2014 Commonwealth Games in his home country of Scotland, at the velodrome in Glasgow that bears his name, but decided to call it quits because he was still “good, but not good enough.”

“I feel I like have got every last ounce of effort and energy out of myself,” Hoy said. “I wouldn’t want to turn up there as a shadow of my former self.”

Hoy, 37, earned six gold medals during his Olympic career on the track, winning his last two in London to surpass legendary rower Steve Redgrave for the most gold by any British athlete. Hoy and fellow British cyclist Bradley Wiggins each own seven Olympic medals in all.

“I think it just dawned on me over time that I am satisfied, happy, content. There is no lingering doubt. I know I have done everything I can and it would be a mistake to go on.”

Hoy was Knighted in 2008 after becoming the first British athlete in a century to earn three gold medals at a single Olympics. And for helping turn Great Britain into a nation recognized for it’s excellence in cycling: Britons won seven of the ten track cycling golds in London, and 12 medals total in the sport.

“Just to see the legacy, not just for myself but for the whole of the sport – to see what we have achieved as a sport over the last 10, 15, 20 years. It’s a huge satisfaction to see the future of the sport flourishing.

“I am going to cycle for the rest of my life. And I hope to encourage other people to get into the sport and ride bikes, too.”

Russian Yevgenia Medvedeva broke the record for highest women’s short program score at the Grand Prix Final on Friday.

Medvedeva, who hasn’t lost in more than one year, totaled 79.21 points in Marseille, France. That beat Mao Asada‘s 78.66 from the 2014 World Championships, the previous record under a decade-old judging system.

“I knew approximately about the record,” Medvedeva said through a translator. “For me, it’s one step further.”

Medvedeva leads Canadian Kaetlyn Osmond by 3.67 points going into Saturday’s free skate. No U.S. woman qualified for the six-skater Grand Prix Final for the first time since 2008.

She already holds the free skate world record and can break Yuna Kim‘s record for total score with a solid effort Saturday in Marseille. Medvedeva said she can perform better than she did Friday, specifically with her program interpretation and spins.

“I always strive for perfection,” she said through a translator. “When you stop doing that, you will stop progress.”

The Grand Prix Final concludes with the women’s and men’s free skates and free dance Saturday (schedule here). NBCSN will air coverage Sunday from 8:30-11 p.m. ET.

Earlier Friday, Russians Yevgenia Tarasova and Vladimir Morozov held onto their short-program lead to win the pairs event by 7.14 points over China’s Yu Xiaoyu and Zhang Hao.

Canadians Meagan Duhamel and Eric Radford, the two-time world champions and pre-event favorites, struggled in the short program and free skate and lost for just the second time in the last three seasons.

In the short dance, Canadians Tessa Virtue and Scott Moir recorded the highest score of all time, an 80.50, to take a 2.53-point lead into Saturday’s free dance.

That Virtue and Moir lead is no surprise — they were the top couple in the fall Grand Prix season — but their closest challenger is a surprise.

It is not two-time world champions Gabriella Papadakis and Guillaume Cizeron of France, but instead Americans Maia and Alex Shibutani, who totaled a personal-best short dance.

Gracie Gold struggled in all four of her competitions this fall, capped by her lowest total score in four years at a Croatian event this week, putting her under scrutiny for the U.S. Championships in six weeks.

She singled three jumps and fell twice across two programs at Golden Spin in Zagreb, Croatia, on Thursday and Friday.

Gold totaled 159.02 points for sixth place, her first time below 160 points since 2012 Skate Canada in her first season as a senior skater.

Italian Carolina Kostner, the 2014 Olympic bronze medalist, won with 196.23 points in her first full competition since the 2014 World Championships.

Earlier this fall, Gold finished last of six skaters in the free skate-only Japan Open on Oct. 1, fifth at Skate America in October and eighth at Trophée de France in November.

Gold has spoken openly about trying to mentally and physically recover from last season’s world championships, where she dropped from first after the short program to finish fourth, and taking weeks off from training in the summer offseason.

Even with the rough skates, Gold still ranks fourth among U.S. women in top scores this season, behind Ashley Wagner, Mariah Bell and Mirai Nagasu.

She could struggle — to a degree — at the U.S. Championships in January and still make the three-woman world championships team. Gold has finished first or second at all four of her senior nationals appearances.
